The first four YouTube videos below feature the beautiful Missa Brevis by Giovanni Perluigi da Palestrina (c.1525-1594), which is one of the pieces RSCM Scottish Voices will be rehearsing during our forthcoming residential rehearsal weekend for use in future services. As an extra treat at the end is the lovely Ave Verum Corpus by William Byrd (c.1539 - 1623) which is on the music list for the same sevice in which we'll be singing the Palestrina Mass.
The Mass recordings below are by the excellent Tallis Scholars (as appears to be the Byrd), and I would recommend buying the CD from Amazon and the sheet music can be downloaded free from CPDL as a PDF from here
For those who know about such things, you may notice that the Credo is missing, but that's simply because we won't be singing that movement in the Mass.
Sanctus & Benedictus
Agnus Dei I & II
